摘要: 基于生态系统服务价值评估模型测算了燕山-太行山区生态系统服务价值,进而系统分析了其动态变化过程,最后对比了生态系统服务价值权衡/协同关系在不同尺度(县域、乡镇、网格)下的空间演变规律。结果表明:(1)燕山-太行山区生态系统服务价值呈持续增加趋势,由2000年的2 985.09亿元增加至2019年的3 171.01亿元。生态系统服务价值在空间上呈东高西低、北高南低的分布特征。(2)各类生态系统服务价值中调节服务占比最高,其后依次为支持、供给和文化服务。各类用地中,林地生态系统服务价值占比最高,其后依次为草地、耕地、湿地、水域和荒漠。(3)协同关系为燕山-太行山区生态系统服务之间的主导关系,权衡关系存在于供给服务与其他3项服务中。不同研究尺度下权衡/协同关系具有差异,县域尺度仅表现出协同关系,而乡镇和网格尺度下协同/权衡关系并存。研究结果对准确把握不同尺度下生态系统服务价值和权衡/协同关系具有重要意义,可为燕山-太行山集中连片特困区生态环境恢复提供科学依据,进而为实现贫困区经济发展与生态保护双赢奠定基础。

Abstract: Taking Yanshan-Taihang Mountains Area as the study area, the ecosystem service value (ESV) was calculated based on the ESV evaluation model. And the dynamic change process of ESV was systematically analyzed. Meanwhile, the spatial evolution of ESV trade-offs/synergies was compared at different spatial scales (county, town and grid). The results show that: (1) In the study area, the ESV increased continuously from 2 985.09×108 yuan in 2000 to 3 171.01×108 yuan in 2019. The spatial distribution of ESV was high in the east and north, and low in the west and south. (2) Among all kinds of ESV, the regulation service was the highest, followed by support, supply, and cultural services. Among all kinds of land use, the ESV of forest was the highest, followed by the ESV of grassland, cultivated land, wetland, water system and desert. (3) Synergies were the dominant relationships between ecosystem services, and tradeoffs only existed between supplying service and the other three services in the study area. The tradeoffs/synergies were different at different space scales (county, town, and grid). The synergies were dominant at county scale, while the tradeoffs/synergies co-existed at town and grid scales. The results are of great significance for accurately understanding the values and trade-offs/synergies of ecosystem services at different scales. It can provide scientific references for ecosystem protection and restoration in the concentrated poor areas of Yanshan-Taihang Mountains, and also lay a foundation for achieving the win-win situation of economic development and ecological protection in poverty areas.

Key words: ecosystem services value, tradeoffs/synergies, Yanshan-Taihang Mountains Area, multi-scale, correlation analysis
